Pith builds it, implements it, trains the team on it, and stays until it runs without us.
That means the engagement is complete when the team can run what was built, not when the build is finished. Pith stays through implementation, through the first months of operation, and through the handover. When Pith goes, the system is in the business, not in Pith's heads.
Structural work requires the founder's involvement at the start and a goal of changing how the business operates. If that's the conversation, Pith is the right partner. If the goal is to improve a specific metric this quarter, Pith will say so in the first call.
